At approx. 1/2″ thick frame, the cage is rock solid and thick enough to mount accessories to any of the available 1/4-20″ or 3/8″ threaded holes over the top and along the sides. The frame can be adjusted to a wider setting if you need additional clearance around the sides. Unfortunately neither the Base or Advanced Kits come with a set of 15mm rails, so you’ll need to provide your own.

I was wondering: If I was to get the basic kit, which does not feature the tophandle nor the top-plate, would I be able to attach the part where the 15mm rods go through to the top of the cage, while attaching a quickreleaseplate directly to the botton of the cage.

Basically just moving the bottom part with the rod-openings to the top and replacing it with a regular, standard QR plate.

@Joroen – The bottom part uses two screws to mount under the camera. I don’t know if it will be a nice fit, but with all the mounting options i’m sure you can find another 15mm clamp to add to the top.

are there 3/8 -16 holes on the sides of the cage? i see markers for the 1/4-20 spots the camera left side but i dont see any for the larger size thread? are the two rounded spots on the right side where the 3/8th threads are? its tough to tell for sure from the pictures.
